However, the main agencies are those regarding primary socialization, which is the process where people learn attitudes, values, and actions appropriate to individuals as members of a particular culture. Secondary socialization agencies are important too.
Measuring great saphenous vein (GSV) diameter is standard in pre-interventional assessment of varicose disorders, but has never been properly validated. This work assessed the relative value of measuring GSV diameter at the most often used sites: the sapheno-femoral junction and the proximal thigh.
ECG paper is a grid where time is measured along the horizontal axis. 1  Each small square is 1 mm in length and represents 0.04 seconds. 2  Each larger square is 5 mm in length and represents 0.2 seconds. Voltage is measured along the vertical axis. 10 mm is equal to 1mV in voltage. The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
